Special
Coverage
Adjustment

Some 2012-2013 model year Chevrolet Equinox or GMC Terrain vehicles, equipped with a 2.4L engine
and certified to the EPA Bin 4 emission standard and the California Cleaner Federal Vehicle option of
Bin 4 emission standard, may exhibit catalytic converter and/or oxygen sensor performance
degradation, without illumination of the malfunction indicator lamp (check engine light), as a result of
excessive engine oil consumption (less than 2,000 miles [3,200 km] per quart [0.946 L] of engine oil)
due to piston ring wear.
This special coverage covers the condition described above for a period of 10 years or 150,000 miles
(241,400 km), whichever occurs first, from the date the vehicle was originally placed in service,
regardless of ownership.
For vehicles covered by Vehicle Service Contracts, all eligible claims with repair orders on or after
October 1, 2020, are covered by this special coverage and must be submitted using the labor operation
codes provided with this bulletin. Claims with repair orders prior to October 1, 2020, must be submitted
to the Service Contract provider.

Correction

Vehicle owners or lessees who paid for repairs referenced in this Special Coverage (“Customers”) are
eligible for reimbursement of their reasonable and customary expenses in accordance with the
procedures specified below. The conditional right to reimbursement is provided by GM solely in the
interest of customer satisfaction and is personal to Customers. Customers may not assign and GM
does not consent to any assignment of any Customer’s right to submit reimbursement claims, or to
receive reimbursement, or any other rights granted by this Special Coverage to any third party,
including but not limited to service contract providers, and this Special Coverage is not intended to
and does not confer any third party beneficiary, subrogation or contribution rights, or any other rights
to reimbursement, against GM, whether in law, equity or otherwise, on any third parties.
Determine if the vehicle has, or has been repaired for, an excessive engine oil consumption condition
due to piston ring wear by
1. Performing an excessive engine oil consumption test, or
2. Examining IVH or other service records to determine if a repair has been performed to remedy
excessive oil consumption due to piston ring wear.
If the vehicle has, or has been repaired for, an excessive engine oil consumption condition due to piston
ring wear, replace the catalytic converters and oxygen sensors.
See also Special Coverage bulletins 16118, N192291100 or N192291101 “Excessive Engine Oil
Consumption” for repair of engine and other components.
Note: The special coverage terms for excessive engine oil consumption may be different than the
special coverage terms for the catalytic converter and oxygen sensor degradation. The repairs will be
made at no charge to the customer.

Service Procedure
Note: If the vehicle you are working on is eligible for special coverage 16118, N192291100 or N192291101, be sure
to perform that before proceeding to this special coverage. Troubleshooting for this issue starts with determining
if the vehicle is experiencing excessive oil consumption, which is the topic of those two special coverage
bulletins.
1.

Check Investigate Vehicle History (IVH) to determine if the pistons and rings were replaced for excess oil
consumption. This can be under Special Coverage 16118, N192291100 or N192291101 or customer pay.
•

If the pistons and rings were replaced for excess oil consumption, under either special coverage OR under
customer pay, replace the front and rear oxygen sensors as well as both catalytic converters. Proceed to step 2.

•

If an excess oil consumption condition is determined to exist using the test procedure in Special Coverage 16118,
N192291100 or N192291101, perform the repair specified in that special coverage. In addition, replace the front
and rear oxygen sensors as well as both catalytic converters.
•

•
2.

If Special Coverage 16118, N192291100 or N192291101 has expired, and the customer refused to repair
the pistons and rings under customer pay, they are still eligible to have the oxygen sensors and catalytic
converters replaced under this Special Coverage. Proceed to step 2.

If the pistons and rings were NOT replaced for excess oil consumption, and the car currently has no oil
consumption issue, no further action is required.

Refer to Catalytic Converter Replacement (LEA-AWD), Catalytic Converter Replacement (LEA-FWD), Three-Way
Catalytic Converter Replacement, Heated Oxygen Sensor Replacement – Sensor 1, and Heated Oxygen Sensor
Replacement – Sensor 2 in SI as necessary to complete repairs.

Courtesy Transportation – For USA & Canada
Courtesy transportation is available for Customers whose vehicles are involved in a product program and still within the
warranty coverage period. See General Motors Service Policies and Procedures Manual for courtesy transportation
program details.
Customer Notification
General Motors will notify Customers of this special coverage on their vehicle (see copy of typical Customer letter included
with this bulletin).

Customer Reimbursement
Customer requests for reimbursement of previously paid repairs to correct the condition described in this bulletin are to
be submitted to the dealer prior to or by October 31, 2021. See General Motors Service Policies and Procedures Manual,
Product Field Action Customer Reimbursement Procedure (USA & Canada) or local Policies and Procedures, for details.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of
conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained
technicians have the tools, equipment, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT
assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See your dealer for information on whether your
vehicle may benefit from the information.

N192287100 Catalytic Converter and Oxygen Sensor Performance
Degradation
October 2020
This notice applies to your vehicle, VIN: _____________________________________
Dear General Motors Customer:
We are writing to inform you of a potential emissions part condition of degraded catalytic converter and/or oxygen
sensors caused by excessive engine oil consumption affecting some 2012-2013 model year Chevrolet Equinox or GMC
Terrain vehicles with a 2.4L engine of the type you own.
The excessive oil consumption issue that causes this emissions parts condition is defined as an engine consuming a
quart of oil or more in less than 2,000 miles [3,200 km] of driving. Signs your vehicle may have excessive oil
consumption include that it needs frequent oil refilling, or that the engine creates an audible rattle or knocking sound, or
that the engine oil pressure warning light illuminates on the instrument panel, or that the following message appears in
the Driver Information Center: “Oil Pressure Low – Stop Engine.”
Do not take your vehicle to your GM dealer as a result of this letter unless you believe that your vehicle has the
condition as described above.
What We Have Done: General Motors is providing owners with protection for this emissions part condition. If your
2012-2013 model year Chevrolet Equinox or GMC Terrain engine is diagnosed with excessive engine oil consumption,
as described above, which causes this condition within 10 years of the date your vehicle was originally placed in service
or 150,000 miles (241,000 km), whichever occurs first, the catalytic converters and oxygen sensors will be replaced for
you at no charge. Diagnosis or repair for conditions other than the condition described above is not covered under this
special coverage program.
What You Should Do: It is a good idea to check the engine oil level at each fuel fill. Your vehicle owner manual has
instructions on checking engine oil in the Vehicle Care section. If you believe that your vehicle has the condition
described above, and it is within both the time and mileage limits set forth above, diagnosis, and repairs and
adjustments if needed, which qualify under this special coverage must be performed by a General Motors dealer. You
may want to contact your GM dealer to find out how long they will need to have your vehicle so that you may schedule
the appointment at a time that is convenient for you. This will also allow your dealer to order parts if they are not already
in stock. Keep this letter with your other important glove box literature for future reference.
Reimbursement: If you have already paid for repairs for the condition described in this letter, please complete the
enclosed reimbursement form and present it to your dealer with all required documents. Working with your dealer will
expedite your request, however, if this is not convenient, you may mail the completed reimbursement form and all
required documents to Reimbursement Department, PO Box 33170, Detroit, MI 48232-5170. The completed form and
required documents must be presented to your dealer or received by the Reimbursement Department by October 31,
2021, unless state law specifies a longer reimbursement period.
The right to submit reimbursement claims is provided by GM solely in the interest of customer satisfaction and is
personal to vehicle owners and lessees who previously paid for repairs referenced in this Special Coverage
(“Customers”). Customers may not assign and GM does not consent to any assignment of any Customer’s right
to submit reimbursement claims, or to receive reimbursement, or any other rights granted by this Special
Coverage to any third party, including but not limited to service contract providers, and this Special Coverage
is not intended to and does not confer any third party beneficiary, subrogation or contribution rights, or any
other rights to reimbursement, against GM, whether in law, equity or otherwise, on any third parties.
If you have any questions or need any assistance, please contact your dealer or the appropriate Customer Assistance
Center at the number listed below.
